Math is rough, even for adults.
For kids it can be very frustrating. Sometimes it's just one of those things that you do not understand. When you get stuck at that wall you need some help getting over. If you don't get over that roadblock then you're never going to progress because math is own of those subjects where everything builds on itself.
Score math tutors are there to help you get your kids past this kind of trouble. They have special training to help kids who are having a bit of trouble. I know that if the Bloglet hits a math wall like this, I'm going to make sure she has the help that a service like Score can provide.
